My invention relates to a sucker or polish rod particularly pertaining to oil wells.

In operating oil Wells where wax from the crude oil accumulates, and although sometimes the accumulation is slow, frequently the v wax in time clogs the tubing so that the sucker or polish rod cannot move up and down freely, or, as frequently happens, cannot, be moved at all. This necessitates pulling the rod out of the tubing, and at times the rod becomes fast in the tubing so that both rod' and tubing have to be pulled at one time.

The general object of my invention is to provide a novel means for preventing the accumulation of wax in the tubing by causing a turning movement to be imparted to the polish rod, thus either keeping the wax pumped out with the oil, or in case the waxhas accumulated, loosening the same so that the sucker rod can be operated freely.

Characteristic features of the invention are that the turning means is associated with an oil Well pumping jack; the sucker rod is turned with the down stroke of the .polish rod and by means of a ratchet; the ratchet is made in halves so that it can be clamped on; the pawlis adapted to be thrown out while the pumping jack is operating; vertical adjustment of the ratchet wheel is provided for so.

that by moving it up or down on the polish rod the motioning part of thewheel by the operating pawl is varied; the gravity method is employed for maintaining the pawl with the ratchet the device may be placed either above the walking beam as illustrated in the drawings, or below the same; the ratchet is merely illustrative of one example of the invention.

In the-illustrated embodiment-of iny invention the numeral 10 indicates a channel beam sill from which a post ll risesstrengthened by a brace 12, saidpost and bracejcon verging at the'upper end to receive a pivot 13 ofthe channel bar walking beam 14. A jack designated generally by the numeral--15 is pivoted below'as at 18 tosill 10 and is operated by a reciprocating rod 16 actu'ated'from any source of power, not shown. The numeral 17 designates a'link 'connectingthe jack with the'walking beam 14,]and the numeral 19 indicates the lower endof-"a clamp to jwhich the link 17 is pivoted by bolt 20. The numeral 21 indicates a'sucken rod orpolish In carrying out myinventiona block22'is secured by a bolt 122 to'thatendof the walk -ing; beam 14 opposite the pivot; 13: of said beam, and to said block22 is securedby abolt 23 a bedplate .24 which-is seatedoli thefbeaxn 14 and which is provided with a guide l25 for the polish rod 2-1, and has trunnions'l26 seated on the bedplate 24 as a bearing. The numeral 27 indicates the polish rod clamp.

In accordance with my invention a'plate28 $5 1 is suitably: fastened for ex ample by bolt 23 to the-bedplate 24, and has'upwardl'y project ing earsf29 between which is secured the lower end of an upwardly extending pawl "31 through the medium Of' l)0lt 30 or other'pivot means. 1Tl1e pawl31 engages a horizontally disposed ratchet wheel 32 held to the polish rod 21 by clamp 34, said ratchet wheel being made in halves. On said pawl 31 on that side toward'the polish rod is{ abalance arm 33 tending to maintain. the'pawl in engagement with the ratchet wheel'32. v

By raising or lowering the ratchet wheel '32 on the polish rod 21 it will be readily understood that the ratchet wheel willbeengaged by a pointon the pawl 31 moreor less distant from the pivot 30 to vary the turning movement imparted to the ratchet Wheel 32 by the pawl 31. In operation the jack frame is vibrated 5 by the rod 16v orotherwise -the jack through the medium of the-link 17 vertically vibrates V the Walking beam 14 on its pivot 13, andas the beam 14 moves downwardly the engage i ment 'of the pawl '31 maintained by the 7 Weight arm 33 Will-cause aturning movement to'be imparted to the'ratchet wheel 32, and,' hence, a turning movement Will'beimparted to the polish rod 21 for preventing the aecu mulation of Wax, or for loosening any Wax 7 7,
